Tropical forests covering an area nearly the size of India are set to be destroyed in the next 35 years, a faster rate of deforestation than previously thought, a study said on Monday.
The Washington-based Center for Global Development, using satellite imagery and data from 100 countries, predicted that 289 million hectares of tropical forests would be felled by 2050. The results will have dangerous implications for accelerating climate change, the study said.
Deforestation is said to contribute to climate change, as forests store carbon while acting as a filter taking carbon dioxide gas out of the atmosphere.
If trends continue, tropical deforestation will add 169 billion tonnes of carbon dioxide to the atmosphere by 2050, the equivalent of running 44,000 coal-fired power plants for a year, the study’s lead author said.
“Reducing tropical deforestation is a cheap way to fight climate change,” environmental economist Jonah Busch said.
He recommended taxing carbon emissions to push countries to protect their forests.
UN climate change experts estimate that nations must keep emissions to one trillion tonnes of carbon to keep global temperature rises below 2°C, the maximum possible increase before catastrophic climate change is predicted to start.
If trends continue, the amount of carbon burned as a result of clearing tropical forests is equal to roughly one-sixth of the entire global carbon dioxide allotment, Busch said.
“The biggest driver of tropical deforestation by far is industrial agriculture to produce globally traded commodities, including soy and palm oil,” he said.
The study predicted the rate of deforestation will climb through 2020 and 2030 and accelerate in about the year 2040 if changes are not made.
There have been some success stories where countries reduced tropical deforestation without compromising economic growth or food production, the study said.
Brazil decreased deforestation in the Amazon rainforest by 80 percent over a decade through the use of satellite monitoring and increased law enforcement, even as cattle and soy production rose, the study said.
‘IN A DIFFERENT PLACE’: The envoy first visited Shanghai, where he attended a Chinese basketball playoff match, and is to meet top officials in Beijing tomorrow US Secretary of State Antony Blinken yesterday arrived in China on his second visit in a year as the US ramps up pressure on its rival over its support for Russia while also seeking to manage tensions with Beijing. The US diplomat tomorrow is to meet China’s top brass in Beijing, where he is also expected to plead for restraint as Taiwan inaugurates president-elect William Lai (賴清德), and to raise US concerns on Chinese trade practices. However, Blinken is also seeking to stabilize ties, with tensions between the world’s two largest economies easing since his previous visit in June last year. At the
Nearly half of China’s major cities are suffering “moderate to severe” levels of subsidence, putting millions of people at risk of flooding, especially as sea levels rise, according to a study of nationwide satellite data released yesterday. The authors of the paper, published by the journal Science, found that 45 percent of China’s urban land was sinking faster than 3mm per year, with 16 percent at more than 10mm per year, driven not only by declining water tables, but also the sheer weight of the built environment. With China’s urban population already in excess of 900 million people, “even a small portion
UNSETTLING IMAGES: The scene took place in front of TV crews covering the Trump trial, with a CNN anchor calling it an ‘emotional and unbelievably disturbing moment’ A man who doused himself in an accelerant and set himself on fire outside the courthouse where former US president Donald Trump is on trial has died, police said yesterday. The New York City Police Department (NYPD) said the man was declared dead by staff at an area hospital. The man was in Collect Pond Park at about 1:30pm on Friday when he took out pamphlets espousing conspiracy theories, tossed them around, then doused himself in an accelerant and set himself on fire, officials and witnesses said. A large number of police officers were nearby when it happened. Some officers and bystanders rushed
Beijing is continuing to commit genocide and crimes against humanity against Uyghurs and other Muslim minorities in its western Xinjiang province, U.S. Secretary of State Antony Blinken said in a report published on Monday, ahead of his planned visit to China this week. The State Department’s annual human rights report, which documents abuses recorded all over the world during the previous calendar year, repeated language from previous years on the treatment of Muslims in Xinjiang, but the publication raises the issue ahead of delicate talks, including on the war in Ukraine and global trade, between the top U.S. diplomat and Chinese
